MDL = Minimum Detection Limit.
PQL = Practical Quantitation Limit
U = Analyte was analyzed for but not detected at the indicated MDL.
Mean = Arithmetic mean of all samples shove the MDL. Samples below the MDL are assigned an assumed 0.5 MDL value in the averaging calculation. If all samples are below the MDL, the
sample mean is reported as U.
